How Much Does Air Conditioning Installation Cost in London?

Air conditioning installation costs in London vary depending on the type of system, the number of rooms and the complexity of the installation.

As a general guide:

Single split-system: £1,500–£3,000

Multi-split system: £3,500–£8,000+

Ducted air conditioning: £6,000–£15,000+

These figures are estimates, and the final cost will depend on your property and requirements.

Several factors can affect the price, including the unit’s size and brand, the distance between indoor and outdoor equipment, electrical work, pipework, access difficulties and whether planning restrictions apply. London properties with limited outdoor space, listed status or strict building-management rules may require additional work.

Be cautious of quotes that appear unusually cheap or do not clearly explain what is included. A professional quotation should cover the equipment, installation labour, pipework, electrical connections, testing, commissioning, warranty details and any optional maintenance plans.

The best way to get an accurate price is to arrange a site survey. A qualified air conditioning engineer can assess the space, recommend the correct system and provide a detailed quote based on your property.
